[Chameleon] Chameleon images access problem ....

Hi Jeremy
As I gather from your postings the chameleon page is loading fine apart from the keymap and main image?
Have you looked at your php log file and session files?
When I experienced this problem it was because a session lock was being generated which blocked the details of the Mapfile being served hence no image.
I suggest doing the following in the php.ini file go to the session section and set
Session.save_handler = files
Session.save_path = c:/Inetpub/wwwroot/tmp
Session.use_cookies = 1
Then reload your chameleon application so it generates the session folder in the specified directory tmp. Check that a lock file is being created.
If it is then go to C:\Inetpub\wwwroot\chameleon\htdocs\common\session\session.php
Comment out the line $szLockFile = $szSessionDir using /* */
Set the variable $GLOBALS [szDebugDir] = "c:/Inetpub/wwwroot/tmp/"
Then reload the application and see if the images appear.
Also to check to see if everthing is configured properly load in your web browser http://yourserver/chamemeleon/admin/main.phtml it provides details of chameleon, cwc2, mapscript and php configuration.
Hope this helps?
